Building a Legacy for Future Texan Scientists

Supporting students today is an investment in the scientists of tomorrow. 

Successfully empowering learners requires a complex strategy. That is why our approach is multifaceted: from cultivating a space for informal learning and community building to developing engaging off-site programs, the Science Mill is dedicated to supporting underserved students in as many ways as possible. 

Conversation Starters: Voice Over

Conversation Starters: Voice Over

Have you explored our Voice Over exhibit at the Science Mill? This unique piece combines art and science to explore communication. When you stand in front of one and whisper, your conversational partner can hear you from 300 feet away!  

Voice Over uses parabolic reflectors to focus sound waves into a single point. This focus allows the sound to travel farther and be heard more clearly at the end focal point.  

If you’re intrigued by the science behind this exhibit, your kids probably are too. We have some conversation starters available to guide discussions on the properties of sound and more!
